Skrip Javascript mengimplementasikan enkripsi halaman web statis

Penulis：Eve Cole Waktu Pembaruan：2009-06-08 18:34:42

Dua hari yang lalu, saya melihat seseorang bertanya tentang enkripsi halaman web statis, jadi saya menulis

ide kode ini:

Saat mengenkripsi: pertama enkripsi kunci pengguna A dengan md5 ke B, kemudian gunakan B untuk XOR file sumber S0 untuk mendapatkan file target S1 , dan simpan S1 ke dalam variabel js.

Saat mendekripsi : Minta kuncinya, lalu operasikan sama seperti enkripsi.

Karena yang digunakan md5, menurut saya pribadi tidak bisa di-crack tanpa kunci (kecuali kekerasan)

Mari kita coba haha:

Kode sumbernya adalah sebagai berikut:

<html> <head> <title>Encoder Web</title> <style> body { ukuran font:12px; tinggi baris:12px; warna latar: lebar tepi:0px margin: 0px; padding:4px; } #t1, #t2 { lebar:100%; tinggi:40%; lebar batas:1px; overflow:auto; } masukan { lebar batas:1px; bantalan-kiri:10px; bantalan-kanan:10px; margin:4px; } </style> <skrip> fungsi webEncode(){ strSource=escape(XOR(t1.value,STR. md5(p1.nilai))); //strSource=t1.value;
